1. Wanting to invite a friend to an event and having to invite his/her boyfriend/girlfriend aswel, even if you don't want the significant other there.
2. Inviting somebody to an event when you desperately don't want them there in order to appear like the better person. This usually requires quite a bit of "down-playing".
1. "Arnold was standing right there when I invited Susan to my birthday, total technicality invite"
2. "Why did you invite all of Rodgers friends"
"They we're all 'technicality invites', you know, so it wouldn't be awkward when they show up anyway..."
